Closure Skirt

The base 1 of the closure devices of the present invention furthercomprises a closure skirt 4. The closure skirt 4 is capable of engagingthe neck finish or container opening of a receiving vessel to providesealed closure of the receiving vessel neck or opening. In someembodiments, the closure skirt 4 has a greater diameter than the sleeveengaging portion of the base 30. The closure skirt 4 has a proximal topor deck, one or more peripheral side walls, and a distal annular edge.As shown in FIGS. 2 and 4, in some embodiments there are one or morelongitudinal finger recess elements 32 on the outer side walls of theclosure skirt 4 for better grasping by the end user. In one embodiment,the closure skirt 4 has threads on the internal side walls capable ofbeing rotatably coupled to a receiving vessel opening. In anotherembodiment the closure skirt 4 is non-threaded. In some embodiments, theclosure skirt 4 comprises one or more depending radial flexible membersthat fits to the inner diameter of a receiving vessel opening. Thedepending radial member is designed to have interfering engagement withthe inner diameter of the opening of a receiving vessel such that itseals the contents of the receiving vessel from leaking out and stillallows sufficiently low application and removal forces to be readilyapplied and removed by the end user. In some embodiments the closuredevices of the present invention are capable of providing sealingengagement with a variety of container neck finishes and containeropening sizes of a receiving vessel and comprises the features andfunctionality as described below for the universal closure skirt.

Sleeve

The closure devices of the present invention comprise a sleeve 12. Thesleeve engages the base 1 and spout 5 of the closure device. In someembodiments, the sleeve 12 is capable of moving in an axial directionrelative to the base 1. In some embodiments, the sleeve comprises acenter post 6 which acts on the end cap 7; a base seal portion of thesleeve 28 which engages the base 1; and a spout seal portion of thesleeve 18 which engages the spout 5. In some embodiments, the base sealportion of the sleeve 28 comprises one or more distal end sleeve beads22 which provide radial interference on the outer diameter of the sleeveengaging portion of the base 30. In some embodiments, the spout sealportion of the sleeve 18 comprises one or more spout seal beads 19 whichprovide radial interference on the inner diameter of the lesser diameterof the spout 27.

In some embodiments, the outer diameter of the sleeve, such as the outerdiameter of the base seal portion of the sleeve 28 comprises one or moresleeve helical thread forms 14 that engage with the inner diameter ofthe dust cover 2 (such as a dust cover helical thread forms 13) suchthat when the dust cover is rotated, this action drives the sleeve 12,including the center post 6 and end cap 7 in a downward direction.Downward vertical movement of the center post 6 moves the end cap 7beyond the distal end of base 1 to effect release of one or moreingredients, formulations or products into a receiving vessel. In someembodiments, the dust cover 2 does not participate in moving the sleeve12 in a downward direction. In some embodiments, the dust cover 2 can beremoved, and the sleeve 12 twisted manually by a user, driving thesleeve 12 in a downward direction, resulting in release of the one ormore ingredients, formulations or products into a receiving vessel.

Center Post

In some embodiments, the center post 6 has a cylindrical, tubular orconical shape. In some embodiments, the center post 6 has one or moreouter diameters, a proximal stem of the center post 8, an intermediateportion and a distal end. In some embodiments the center post 6 furthercomprises one or more inner diameters. In some embodiments the outer andinner diameters of the center post 6 are variable along the length ofthe center post 6. In some embodiments, the proximal top of the stem 8can be flat or rounded. In one embodiment, the proximal stem of thecenter post 8 has a greater outer diameter than the intermediateportion, distal end and/or a combination thereof. In some embodiments,the diameter of the stem of the center post 8 is greater than at leastthe intermediate portion of the center post in a stepped, non-taperedfashion such that there is a distal annular edge of the stem. In otherembodiments, the outer diameter of the center post 6 is substantiallythe same along its length. In some embodiments, the distal end of thecenter post 6 is configured to be in mating engagement with the end cap7. In some embodiments, the center post 6 is configured to be in axialalignment within the product chamber 3.

Upon application of a user-actuated twisting force of the dust coverand/or sleeve, the center post 6 is capable of moving axially in adownward vertical or distal direction toward the distal end of the base1. Distal movement of the center post 6 moves the end cap 7 in thedownward or distal direction beyond the distal end of the base 1 toeffect release of the one or more stored ingredients, formulations orproducts.

In some embodiments, the center post 6 is substantially rigid and notintended to bend or flex to a deformable position. In some embodiments,the rigidity of the center post 6 aids assembly so that it can readilyaccept the end cap 7 in interfering engagement. In some embodiments thecenter post 6 is intended to remain engaged in the end cap 7 and not bereadily removed from the end cap 7. Upon application of user-actuatedtwisting force acting on the sleeve, the center post 6 forces the endcap 7 in a downward or distal direction beyond the distal end of theproduct chamber 3. In some embodiments, the strength of the center post6 needs to be structurally sound enough to forcibly remove the end cap 7from the product chamber 3 where there is diametrical interference.

In some embodiments, the center post 6 is attached, e.g., to the insidediameter of the side walls of the sleeve 12 by one or more center postcollar support ribs 15. In some embodiments, the center post collarsupport ribs 15 can radiate from the inner diameter of the base sealportion of the sleeve 28, spout seal portion of the sleeve 18, orcombinations thereof. In some embodiments, the center post collarsupport ribs 15 are static and maintain the static position of thecenter post relative to the other sleeve portions. In other embodiments,there are optionally one or more flexible hinge leg members in additionto or in lieu of center post collar support ribs 15 to help maintainaxial alignment of the center post 6. In some embodiments, the flexiblehinge leg members can be attached to the inner diameter of the base sealportion of the sleeve 28, or the spout seal portion of the sleeve 18 orcombinations thereof and radiate therefrom and attach to the center post6 when used in lieu of center post collar support ribs 15. In someembodiments, flexible hinge leg members can be attached to the side wallof the product chamber 3, the inner diameter of the base seal portion ofthe sleeve 28, the spout seal portion of the sleeve 18 or combinationsthereof and radiate therefrom and attach to the center post 6 when usedin addition to the center post collar support ribs 15. In someembodiments, flexible hinge leg members can radiate perpendicularly fromthe inner diameter of the product chamber 3. In other embodiments,flexible hinge leg members can radiate at a non-perpendicular angle. Insome embodiments, flexible hinge leg members can attach to the proximalstem of the center post 8. In some embodiments, the flexible hinge legmembers attach to the intermediate portion of the center post. Theflexible hinge leg members are capable of flexing and bending. In someembodiments, when the center post 6 is in its inactivated position(i.e., prior to point-of-use dispensing of stored one or moreingredients, formulations or products), the flexible hinge leg membersare not in a flexed or bent position. In some embodiments, the flexiblehinge leg members bend in the distal direction as the center post 6 ismoved in the distal direction by a user-actuated force. When the centerpost 6 is in its activated position (i.e., after point-of-use dispensingof stored one or more ingredients, formulations or products), theflexible hinge leg member is in a flexed or bent position.

Stem of the Center Post

The stem of the center post 8 is the proximal end of the center post 6.The stem of the center post 8 physically closes the outlet 17 when it isin interfering engagement with the outlet 17. The stem of the centerpost 8 is in interfering engagement with the outlet 16 when the spout 5is in its downward or distal most position.

End Cap

The end cap 7 is situated at the distal end of the product chamber 3 inan inactivated state. In some embodiments, the end cap 7 has a proximaltop, peripheral radial edge and distal end.

In some embodiments, the proximal top of the end cap 7 is in matingengagement with the distal end of the center post 6 as exemplified inFIGS. 3 and 6. In some embodiments, mating engagement of the center post6 and end cap 7 maintains axial alignment of the center post 6 withinthe product chamber 3 and facilitates movement of the end cap 7 forrelease of one or more ingredients, formulations or products. In someembodiments, the proximal top comprises a proximally situated recess orcenter post receiving portion 10 (FIGS. 3 and 6). The end cap 7 isconfigured to receive the distal end of the center post 6 in the centerpost receiving portion 10. In some embodiments, there are one or moreradial protrusions in the center post receiving portion 10 for sealingengagement. In other embodiments, as exemplified in FIGS. 3 and 6, thedistal end of the center post 6 is configured to receive the proximalend of the end cap 7. In one embodiment there is center post matingcolumn located on the proximal end of the end cap 7. In someembodiments, the center post mating column is configured to mate withthe inner diameter of the distal end of the center post 6.

In some embodiments, the peripheral radial edge of the end cap 7 is ininterfering engagement with the inner diameter of the side walls of theproduct chamber 3. The interfering engagement is sufficient to providesealing integrity alone and maintain the one or more ingredients,formulations or products in the product chamber 3 of the base 1 untilactuation of the dispenser. In some embodiments, the peripheral radialedge of the end cap 7 and inner diameter of side walls of the productchamber 3 are made of highly polished radial mating surfaces 11. Thesehighly polished radial faces 11 when in intimate contact providesuperior seal integrity against moisture and maintain product integrity.In some embodiments, the end cap 7 is comprised of propylene and/orethylene materials.

Upon application of a force upon the center post 6, the center post 6,moving axially in a downward or distal direction, moves the end cap 7 inthe downward or distal direction below or distal to the distal end ofthe product chamber 3. Distal movement of the end cap 7 reveals adispensing port 58 at the distal end of the product chamber 3. In theinactivated state (i.e., prior to point-of-use dispensing of stored oneor more ingredients, formulations or products) the end cap 7 closes thedistal end of the product chamber 3. In the actuated state (i.e., afterpoint-of-use dispensing of stored one or more ingredients, formulationsor products), the distal end of the product chamber 3 is an opendispensing port 58.

In some embodiments, the proximal top of the end cap 7 further comprisesa tapered end cap surface 9 also referred to as seal shoulder 9. Thedownward angled tapered end cap surface 9 facilitates dispensing of theone or more ingredients, formulations or products of the product chamber3 into the receiving vessel.

In some embodiments, the end cap 7 can be configured to include a linerin between the distal end of the center post 6 and the proximal surfaceof the center post receiving portion 10 in mating engagement with thedistal end of the center post 6. The liner can provide a sealinginterface and added removal resistance. In some embodiments, a smallfoil disc with materials coated on the outside can be cut and placedinto the bottom of the proximal center post receiving portion 10 of theend cap 7 formed to accept the center post 6. In some embodiments, theliner welds to both portions, the end cap 7 and the center post 6 at thecenter post receiving portion 10 using an RF (radio frequency) sealingprocess common in the foil liner applications. Welding with this type ofliner has several advantages (i) the strength of the weld is very strongsuch that the end cap 7 cannot be readily separated from the center post6; (ii) the weld is more targeted (than spin welding, sonic welding andheat stake welding), thus avoiding adhering other nearby portions of thedevice like the outer portions of the end cap 7 to the base 1.

In some embodiments, the distal end of the end cap 7 comprises a distalannular edge. In some embodiments, the distal end of the end cap 7further comprises a flat end surface. In some embodiments the distal endof the end cap 7 is configured to have one or more distal recesses 33 asillustrated in FIG. 7. The one or more distal end cap recesses 33 canprovide a space for any residual plastic from the molding process toremain out of the way and alleviate risk of the residual plasticpuncturing the end plate seal (as described below) if provided. In someembodiments, the distal end cap recesses 33 are situated centrally,flank the center post receiving portion 10, and/or a combinationthereof.

In another embodiment, the center post receiving portion 10 comprisestwo distally located spaces 34 (FIG. 7). These spaces are provided toreceive center flash resulting from the molding process of the closuredevice. The center flash spacing 34 retains the center flash so to avoidinterference with, the mechanics of the closure device, and end cap 7placement helping to maintain proper axial alignment.

In some embodiments, the center post 6 and end cap 7 are configured indimension such that the end cap 7 is flush with the distal end ofproduct chamber 3 in the inactivated state. In other embodiments, thecenter post 6 and end cap 7 are configured in dimension such that theend cap 7 sits proximal to the distal end of product chamber 3 in theinactivated state (FIG. 7). The later embodiment is useful for closuredevices comprising an end plate seal (as described below). In someembodiments, the end cap 7 in a non-flush more proximal position to thedistal end of the base 1 in the inactivated state improves the radialseal of the end plate seal (as described below) to the distal annularedge of the base and/or product chamber 3. It ensures that the end plateseal will attach properly to the distal annular edge of the base 1 andavoids end plate seal contact with the end cap 7 itself and avoidssealing the end cap 7 to the base 1. In other embodiments, the end cap 7together with the distal end of the base 1 and/or product chamber 3protrudes beyond the distal annular edge of the closure skirt 4.

End Plate Seal

In some embodiments an end plate seal is used to provide a protectiveseal at the distal annular edge of the product chamber 3. The end plateseal extends across the distal end of the product chamber 3. The endplate seal is sealed at the distal annular edge of the product chamber3. The end plate seal may be made from a variety materials that are thinand frangible in nature to shear or fracture upon application of aforce. In some embodiments, the center post 6 engaging the end cap 7applies force against the end plate seal causing the end plate to shearand fracture. In some embodiments a foil liner is applied at the distalend of the end cap 7 and distal end of the product chamber 3 to seal theinterior of the base 1. In some embodiments, the closure created by theend plate seal is used to add to product efficacy and provide tamperevidence if prematurely breached.

In other embodiments, a foil end plate seal is supported by plasticacross the entire face of the foil to provide sufficient mechanicalsupport to pass common shipping, filing and drop tests and to maintainproduct integrity. Use of a supporting plastic also allows for amajority of the foil to be intimately attached to the material used tomold the closure device components, such as polypropylene (PP) and highdensity polyethylene (HDPE) polymers, thereby reducing the amount offoil particulates falling into the receiving vessel upon dispensing thecontents of the product chamber 3. In some embodiments, the plasticlining also reinforces the seal for purposes of ingredient freshness andproduct integrity.

Spout

The closure devices of the present invention comprise a spout 5 fordispensing the product for consumption. In some embodiments, the spout 5comprises an outlet 17. Other embodiments and details of the componentsand features of the spout 5 of the present invention are describedbelow.

In some embodiments, the spout 5 is capable of moving axially indownward and upward directions. In some embodiments, the spout 5 ismoved by pulling forces to open the spout 5 pushing forces to close thespout 5. In other embodiments the spout 5 is moved by rotation, whereinone or more helical elements on the spout and/or sleeve cooperate tomove the spout in an upward and downward direction relative to thesleeve depending on whether the spout is being opened or closed.Application of a user-actuated rotating/twisting or pulling forceapplied to the spout 5, moves the spout 5 in an upward direction towardthe proximal end of the closure device. The upward movement of the spout5 concomitantly causes the stem of the center post 8 to break the sealwith the sealing member 21 and expose the outlet 17 of the spout.Application of a user-actuated rotating/twisting or pushing force willmove the spout in the down, distal direction, closing the spout.

In some embodiments, in the inactivated and actuated states, the spout 5interferingly engages the outer diameter of the side wall of the spoutseal portion of the sleeve 18. In some embodiments, the one or moreinner diameters of the side walls of the spout 5, e.g., the lesserdiameter of the spout 27 interferingly engages the one or more outerdiameters of the side wall of the spout seal portion of the sleeve 18.In some embodiments, the inner diameter of the side walls of the lesserdiameter of the spout 27 are threaded, the outer diameter of the sidewalls of the spout seal portion of the sleeve 18 are threaded, or bothare threaded. In some embodiments, the one or more inner diameters ofthe side walls of the lesser diameter of the spout 27 comprise one ormore distal end spout beads 20. The one or more distal end spout beads20 interferingly engage the outer diameters of the side walls of thespout seal portion of the sleeve 18 to provide a leak free seal. In someembodiments the one or more outer diameters of the side walls of thespout seal portion of the sleeve 18 further comprise one or spout sealbeads 19. The one or more spout seal beads 19 interferingly engage theinner diameters of the side walls of the spout, e.g., the lesserdiameter of the spout 27 to provide a leak free seal. In some otherembodiments there is a combination of one or more spout seal beads 19and one or more distal end spout beads 20. In one embodiment, the distalend spout bead 20 is situated distally to the spout seal bead 19. Whenthe spout 5 is in its activated and proximal most position, the one ormore distal end spout bead 20 interferingly engage the spout seal bead19. When the spout 5 is in its closed state and downward or distal mostposition, the one or more distal end spout beads 20 do not engage theone or more spout seal beads 19.

In some embodiments, the closure device of the present inventioncomprises a pull open spout. Some embodiments with a pull open spout areshown in FIGS. 3 and 6. The spout 5 is pulled up or vertically in theproximal direction to open the spout outlet 17 for consumption. Thespout outlet 17 may be closed by pushing the spout down or in the distaldirection. The spout outlet 17 may be opened and closed multiple times.

In one embodiment, there is a pull open spout comprising a greaterdiameter of the spout 24, a lesser diameter of the spout 27, and anoutlet 17. In some embodiments, the spout is configured with aproximally located outlet 17 which is capable of receiving the stem ofthe center post 8. In some embodiments, after dispensing the one or moreingredients, formulations or products of the product chamber 3 into areceiving vessel, the stem of the center post 8 is substantially flushwith the proximal top of the spout 5 and in interfering engagement withthe outlet 17, thereby closing the spout. After dispensing, axial orvertical movement of the spout 5 in the upward direction disengages thestem of the septum 8 from the outlet 17 and opens the spout. Axial orvertical movement of the spout 5 in the downward direction re-closes thespout such that the stem of the center post 8 is in interferingengagement with the outlet 17 again. In some embodiments, the spoutcomprises a sealing member 21 that facilitates closure of the spout 5 tocreate a high integrity seal.

In some embodiments, the proximal top of the spout 5 can be flat orangled. In some embodiments the proximal top of the spout 5 has agreater diameter than the side walls of the spout that are more distalto the outlet 17. The greater diameter of the proximal top of the spout24 can make it easier for an end user to grasp the spout 5 to pull itopen. In other embodiments the proximal top of the spout hassubstantially the same diameter as the side walls of the spout portionthat engages the sleeve 12.

The one or more side walls of the spout 5 have one or more inner andouter diameters. The one or more inner diameters of the side walls ofthe spout 5 interferingly engage the one or more outer diameters of theside walls of the sleeve 12. In some embodiments, the one or more innerdiameters of the side walls of the spout 5 are threaded, the one or moreouter diameters of the spout seal portion of the sleeve are threaded, orthe combination is threaded. In some embodiments, the one or more innerdiameters of the side walls of the spout 5 further comprise one or moredistal end spout beads 20. The one or more distal end spout beads 20interferingly engage the outer diameters of the side walls of the spoutseal portion of the sleeve 18 to provide a leak free seal. In someembodiments, the one or more outer diameters of the side walls of thespout seal portion of the sleeve 18 further comprise one or more spoutseal beads 19. The one or more spout seal beads 19 interferingly engagethe inner diameters of the side walls of the spout to provide a leakfree seal. In some embodiments, there is a combination of one or morespout seal beads 19 and one or more distal end spout beads 20. In oneembodiment a distal end spout beads 20 is situated distally to a spoutseal beads 19. When the spout 5 is in its upward or proximal mostposition, the one or more spout seal beads 19 interferingly engage theone or more distal end spout beads 20 to stop further upward movement ofthe spout 5.

In some embodiments, the side walls of the spout 5 further comprise oneor more radial protrusions. The one or more radial protrusions are usedto make it easier for an end user to grasp the spout for pulling openand pushing close the spout.

Outlet

The outlet 17 is an opening through which contents of a receiving vesselmove through for consumption by an end user. In some embodiments, theoutlet 17 sits in the proximal top of the spout 5. In some embodiments,the outlet 17 comprises an inner radial edge. In some embodiments, theoutlet 17 is capable of receiving and engaging the stem of the centerpost 8. In some embodiments, the inner radial edge of the outlet 17interferingly engages the outer diameter of the stem of the center post8. The outer diameter of the stem of the center post 8 engages the innerradial edge of the outlet 17 to close the outlet 17. When the stem ofthe center post 8 is disengaged from the inner radial edge of the outlet17 there is an opening connecting the product chamber 3 to the outlet 17to allow contents of a receiving vessel to be consumed.

Dust Cover

The closure device of the present invention comprises a dust cover 2. Inthe inactivated state, in some embodiments, the dust cover 2 covers thespout, sleeve and portions of the base. In some embodiments, the dustcover comprises one or more dust cover helical thread forms 13 whichengage one or more sleeve helical thread forms 14. Rotation or twistingof the dust cover drives the sleeve and end cap in a downward direction,from the closed position to an open position, resulting in release ofthe contents of the product chamber into a receiving vessel. In someembodiments, the dust cover 2 can then be removed from the base. In someembodiments, the spout 5 can be pulled open (or rotated/twisted) by auser so that the combined contents of the receiving vessel can beemptied through the spout 5.

In some embodiments, the dust cover is held in position on the closureby a series of lug 56 and groove 57 combinations configured to move/workin combination with the sleeve 12 such that the dust cover is notreadily removed from the base until appropriate lug 56 and groove 56combinations are aligned. Referring to FIGS. 5 and 6, in someembodiments, a dust cover lug element 56 can be located at the distalend of the dust cover 2 which can engage with a groove element 57located on the deck of the base 1. In some embodiments, the alignment ofthe dust cover lug element 56 and the dust cover groove element 57 andthe radial movement required to make the dust cover 2 align for removaldrives the sleeve 12 and end cap 7 from the closed position to the openposition. The dust cover lug 56 and cooperating groove sequence 57 inthe base portion do not allow a user access to ingredients prior totheir release from the product chamber 3 past the end cap 7 into anappropriate receiving vessel.

In some embodiments, the dust cover comprises elements that allow it tobe easily grabbed and/or twisted. In some embodiments, one or more outergripping lugs 26 can be spaced around the dust cover 2, as shown in FIG.2.

In some embodiments, the distal end of the dust cover 2 engages the deckof the base 2. In some embodiments, a rim feature 29 on the closureskirt deck 35 is positioned at the outer diameter of the dust cover 2.In some embodiments, the rim feature 29 helps to stabilize the dustcover 2 and properly align it on the closure device.

In another embodiment, theinner diameter 39 of the side walls 36 is curved and the outer diameter40 of the side walls 36 is angular.

In some embodiments, the inner diameter 39 of the side walls 36 of theclosure skirt further comprises one or more deformable dependingprotrusions 41 of varying dimension to provide a one-fit-many aspect ofthe closure devices of the present invention. In some embodiments, thedeformable depending protrusions 41 are thin, flexible and deformablesuch that the closure can accept a variety of threaded neck and openingdiameters and thread profiles. The one or more deformable dependingprotrusions 41 provide application and removal torque. In oneembodiment, the one or more deformable depending protrusions compriseradial rings 42, helix 43 or combinations thereof. In one embodiment asshown in FIG. 10, the closure skirt has threads on the internal sidewalls capable of being rotatably coupled to a container neck of areceiving vessel. The threads may be of a variety of configurationsand/or helix or pitch. In some embodiments, the helix has a pitch fromabout 0 degrees to about 10 degrees. In other embodiments the helix hasa pitch greater than 0 degrees to about 4 degrees. In anotherembodiment, the one or more deformable depending protrusions 41 comprisemore than one axial rib including vertical ribs 44, angled ribs 45,arced ribs 46, various other shapes or geometries, or combinationsthereof. In other embodiments the one or more deformable dependingprotrusions 41 comprise more than one radial rib, including horizontalribs, angled ribs, arced ribs, various other shapes or geometries, orcombinations thereof. In other embodiments, the deformable dependingprotrusions comprise a combination of radial rings, helix, axial ribs orradial ribs.

The deformable ribs (e.g., 44, 45, 46) are placed in separation on theinner diameter of the side walls to provide application and removaltorque. The axial ribs are compliant through their vertical length andwill shear readily from the top wall to provide a hinged deformablemember with the side wall of the closure. The axial ribs are attached tothe underside proximal top end of the closure for manufacturingpurposes. The axial ribs are designed in such a manner that the proximalend tears or breaks away from the closure when the closure is beingapplied to a container. Attachment at the underside of the proximal top35 is in one embodiment sharp such that is there is no fillet radii. Inanother embodiment, there is a small fillet radii where the side walls36 meet the underside of the proximal top 35 as long as it will notinterferingly engage with the neck or opening of a receiving vessel whenthe closure is applied.

In some embodiments, the depth of a deformable depending protrusion fromthe side wall can range from about 0.005 to about 1.0 inches. In oneembodiment, the depth from the side wall is about 0.040 inches. In someembodiments, the thickness of an axial rib is from about 0.005 inches toabout 0.050 inches. In one embodiment, the thickness of the axial rib isabout 0.020 inches.

In another embodiment, the universal closure skirt comprises a proximaltop 35, one or more peripheral side walls 36, a distal annular edge 37and a depending plug seal 47. The inner diameter 39 of the side walls 36is non-threaded and has no deformable depending protrusions of varyingdimensions 41-46. In other embodiments, there is more than one spacerrib, and/or more than one thread engagement lug, each as describedbelow.

Plug Seal

As shown in FIG. 8 the closure skirt in some embodiments also comprisesa depending radial flexible plug like sealing member 47 that fits to theinner diameter of a receiving vessel neck. This plug seal 47 is uniquein its configuration such that it provides sealing engagementopportunities to a multiplicity of neck finish inner diameters. As shownin FIG. 8, the plug seal protrudes inside the opening of a containerkeeping its contents secure from leakage. The plug seal 47 is designedto have interfering engagement with the inner diameter of the opening ofa container neck such that it seals the contents of the container fromleaking out and still allows sufficiently low application and removalforces to be readily applied and removed by the end user.

The plug seal depends from the underside of the proximal top 35 of theclosure. The dimensions of the plug seal 47 may vary. In someembodiments, the plug seal 47 has a longer and thinner lower or distallead in section 48 that can be readily folded or deformed out oflocation providing interfering engagement for larger inner diameterbottles and a thicker upper or proximal radial sealing section 49 forsmaller inner diameter bottles. In some embodiments, the plug seal 47has a smaller diameter at its distal end with increasing diameter movingtoward the deck or proximal top of the closure skirt. The configurationof the plug seal 47 can be bean-shaped, angular or other shapes andgeometries to provide interfering sealing engagement for container neckswith openings of a smaller inner diameter at the lower distal end of theplug seal and interfering sealing engagement for container necks withopenings of a larger inner diameter at the upper proximal end of theplug seal.

In another aspect, the present invention provides an improved plug sealshape that facilitates manufacturing. Viewed in cross section of FIG. 8,the plug seal is angled in shape, such that the apex 50 of the angleinterferingly engages the inner diameter of a container neck. Theproximal end 49 is larger than the distal end 48. The plug seal's angledsurface (viewed in cross section) interior portion is not parallel tothe outer sealing profile. The inside surface of the improved plug sealhas an interior shape that tapers away from outer surface. Thesediffering tapers allow the intended angular shape to be ejected from thecavity forming steel without the need for additional steel movement forejection from cavity forming steel. The improved angular shape of theplug seal eliminates the need for floating steel components to releasethe undercut from the mold, yet provides interfering radial engagementto the inner diameter of the neck of a receiving vessel to maintainproper seal integrity. The improved plug seal may be used in combinationwith the disclosure devices of the present invention in addition toother dispensing closure devices.

In some embodiments, the length of the plug seal from its proximal endto the distal end is substantially the same length as the side walls ofthe closure skirt 36 such that the distal edge of the internal closurediameter is substantially flush with the distal annular edge of the sidewalls. In other embodiments, the length of the plug seal 47 from itsproximal end to the distal end is less than that of the side walls ofthe closure skirt 36.

In some embodiments as shown in FIG. 8, the plug seal 47 creates aninternal spacing diameter 51 that allows the plug seal to bend andconform to varying container neck finishes and diameters. The internalspacing diameter 51 spans from the inner diameter of the plug seal tothe outer diameter of the base housing 2 within the closure side walls36. The width of the internal spacing diameter 51 may vary to provideinterfering engagement with varying inside diameters of container necks.

In another embodiment, there is a plurality of sealing beads at variedpositions on the plug seal. In some embodiments, the sealing beads areradial bumps that interferingly engage the inner diameter of the openingof a container to close the opening. In some embodiments, the sealingbeads can be positioned at various locations and of varying sizes toengage the neck or opening of a container of various sizes. In oneembodiment, the sealing beads are of a smaller size at the distal end ofthe plug and increase in size moving toward the proximal top of the sealplug. The sealing beads work such that if a closure does not go all theway down to engage the top of the neck or opening of a container, then aset of sealing beads engage the internal diameter of the opening or neckof a container to create a seal and close the opening. In oneembodiment, the smaller and more distal sealing beads will engage theinner diameter of smaller openings and the larger more proximal sealingbeads engage the inner diameter of larger openings.

Spacer Rib

As shown in FIGS. 9-18, the universal closure skirt may further comprisemore than one spacer rib 53 used to provide interfering engagementwithout increasing radial torque. The spacer ribs 53 are connected tothe inner diameter 39 of the side walls 36 of the closure skirt and inone embodiment diametrically opposed which allows the thread to fit inbetween the protrusions 41-46 allowing the closure skirt 4 to conform toan oval shape. In other embodiments, the spacer ribs are spaced apartfrom each other. The vertical position of the spacer ribs on the innerdiameter is important to provide vertical interference with the outerdiameter of the container neck finish thread. The spacer ribs 53 in oneembodiment are situated to mate with the inside proximal top 35 of theclosure skirt 4. In another embodiment, the spacer ribs 53 are situatedbelow the proximal top 35. In some embodiments, the width of a spacerrib 53 is in the range of about 20 mm to about 28 mm for closure devicesfitting about 26 mm to about 28 mm container neck or opening sizes. Thelength of a spacer rib 53 should be in the range of about 2 mm to about20 mm for closure devices fitting about 26 mm to about 28 mm containerneck or opening sizes. For larger diameter container neck or openingsizes there are, in some embodiments, larger dimensioned spacer ribs. Insome other embodiments, there are more than two spacer ribs for largerdiameter container necks or opening sizes. As the size of the containerneck increases, more spacer ribs provide more interference with thecontainer neck to secure the universal closure skirt and to prevent theclosure from disengaging upon shaking

Thread Engagement Lug

As illustrated in FIGS. 18 and 19, the universal closure skirt may alsocomprise more than one thread engagement lug 54 used to meet and provideinterfering engagement with a variety of thread configurations and helixof varying pitch of the container neck engaged by the universal closureskirt. The thread engagement lugs 54 are connected to the inner diameter39 of the side walls 36 of the closure skirt and in one embodimentdiametrically opposed. In other embodiments, the thread engagement lugs54 are spaced apart from each other. The radial spacing between thethread engagement lugs allows the closure skirt 4 to deform duringapplication to a container neck. The vertical and radial positions ofthread engagement lugs are defined such that they will engage threads ona variety of neck finishes within a range. The thread engagement lugscan be in horizontal alignment or off set vertically and radially toprovide optimal thread to neck finish engagement. For larger diametercontainer neck or opening sizes there are, in some embodiments, largerdimensioned thread engagement lugs. In some other embodiments, there aremore than two thread engagement lugs for larger diameter container necksor opening sizes. As the size of the container neck increases, morethread engagement lugs provide more interference with the container neckto secure the universal closure skirt and to prevent the closure fromdisengaging upon shaking

FIG. 18 shows the thread engagement lug 54 in radial alignment with thespacer rib 53 on the inner diameter of the universal closure skirt. Thespacer rib however occupies different vertical space from the threadengagement lug. The spacer rib 53 is more proximal in relation to theposition of the thread engagement lug 54 which is more distallysituated. In other embodiments, the thread engagement lugs are notradially aligned with the spacer ribs, and appear in overlapping oralternating positions along the radial inner diameter while stillmaintaining different vertical space. The radial spacing between thethread engagement lugs and the spacer ribs allows the closure skirt 4 todeform during application to a container neck.

Spacing Diameter

In some embodiments, the universal closure skirt comprises a spacingdiameter 51 that provides clearance for the neck of a container engagedby the universal closure skirt. The spacing diameter allows for the plugseal to move as needed for a proper fit. The spacing diameter spans fromthe inner diameter 4 of the sidewalls 36 of the closure skirt to theouter diameters of the plug seal 47. For larger diameter container neckor opening sizes, in some embodiments, the spacing diameter is largersized.

Thinning Ribs

As illustrated in FIG. 19, in some embodiments, the universal closureskirt comprises one or more thinning ribs 55 to add flexibility to theside walls 36 of the closure skirt. Added flexibility in the skirtallows the closure to conform to larger container neck diameters andconform to oval shaped container neck diameters. The thinning ribs 55may be axial, radial, angled, arced, various other shapes or geometries,or combinations thereof. The thinning ribs 55 comprise one or more areasof the outer diameter 40 of the side walls of the closure skirt wherethe side wall material is thinned enough to provide flexural deformationof the closure skirt when interference with the spacer ribs is createdduring application to the threaded container neck.

Foil Seal

In yet other embodiments, the closure skirt of the present inventioncomprises a distal foil seal to provide sterility to the inside of theclosure skirt and underside of the closure housing. The foil seal spansacross the outer most and distal most diameter of the closure device.

Container Openings and Neck Finishes

The closure skirt can be designed to fit a variety of neck finishes,thread profiles and container opening sizes of variouscontainers/receiving vessels. The container may have a neck or othersuitable structure defining the container mouth or opening. The neck mayhave a circular cross-sectional configuration or some otherconfiguration like an oval or other elliptical, angular cross-sectionalshape. The universal closure skirt may be configured to provide sealingengagement with container necks of varying dimension. In someembodiments, the universal closure skirt is configured to providesealing engagement with container necks having a diameter from about 10mm to about 45 mm.

It is another aspect of the present invention to provide closure devicesas described above that indicate to the end user whether inadvertentrelease of stored one or more ingredients, formulations or products hasoccurred and that protects the user from accidental, inadvertent orpremature dispensing.

Tamper Evident Bands

In some embodiments of the closure devices of the present invention, theclosure skirt 4 has a frangible tamper evident (TE) band removablyattached to its distal annular edge 37 that interferingly engages withthe neck of an attached receiving vessel to prevent removal of theclosure device. In one embodiment, there is a pull tab that when pulledbreaks the TE band away from its engagement with the closure skirt 4. Inanother embodiment, the TE band is attached by one or more break-awaytabs such that application of a twisting motion of the closure skirt 4in a counter clock wise direction breaks the TE band away. A TE bandthat is not in interfering engagement with the receiving vessel at pointof use is indicative of tampering. The closure skirt 4 can be used withor without the depending tamper evident skirt band.

In some embodiments of the closure device, the closure comprises afrangible spout TE band removably attached to the spout, such as thedistal annular edge of the spout 5. In some embodiments, the spout TEband can interferingly engage a radial bead on the sleeve and/or spout.In some embodiments, the spout TE band surrounds the sleeve 12 toprevent inadvertent or premature upward pulling of the spout 5. In oneembodiment, there is a pull tab that when pulled breaks the spout TEband away from its engagement with the sleeve and/or spout.

A removed spout TE band or a spout TE band that is not in interferingengagement with the distal end of the spout 5 at point of use isindicative of tampering.

TE bands can also be attached to the dust cover 2 to prevent inadvertentactuation. The TE bands can be configured with a pull tab which can beremoved prior twisting and/or removal of the dust cover 2.
